ci: Bump GCC snapshot major version to 17
See https://gcc.gnu.org/pipermail/gcc/2026-April/248048.html.
What changed, and why it matters
This commit simply updates the version number of an experimental GCC compiler snapshot used in automated testing, from version 16 to version 17. It is a routine CI/infrastructure maintenance change with no security relevance.
No security action needed; treat as routine CI maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch changes a single Dockerfile build argument, GCC_SNAPSHOT_MAJOR, from 16 to 17 in ci/linux-debian.Dockerfile. This controls which upstream GCC snapshot is compiled and installed for continuous integration jobs. There is no code change, no cryptographic change, and no vulnerability fix or introduction.
